Почему String.Equals не работает?

/ 16 мая 2018

Мой друг и я работаем над простым консольным приложением, чтобы попытаться научиться кодировать C #. У нас работает генератор случайных вопросов, и мы можем принять входные данные. Однако у нас есть проблема, когда независимо от того, что мы вводим, код всегда говорит, что это был неправильный ответ. Мы хотим, чтобы это говорило, что это был правильный ответ или неправильный ответ, как обычные пустяки. Чтобы проверить, является ли ответ правильным или неправильным, мы используем String.Equals, чтобы проверить, совпадает ли ответ с ответом, сохраненным в массиве. Нам любопытно, что мы здесь делаем неправильно и как сделать так, чтобы оператор if работал правильно. 

static void Main(string[] args)
    {
        //Random number generator
        Random rnd = new Random();
        int randInt = rnd.Next(0, 9);

        //Questions array Question/Answer
        string[,] array2D = new string[10, 2] {
            { "Mario Kart is a video game series publish by which company?", "Nintendo" },
            { "What was the first console video game that allowed the game to be saved?", "The Legend of Zelda" },
            { "The Connecticut Leather Company later became what toy company that was popular in the 1980s for its Cabbage Patch Kids and video game consoles?", "Coleco" },
            { "Nintendo is a consumer electronics and video game company founded in what country?", "Japan" },
            { "The first person shooter video game Doom was first released in what year?", "1993" },
            { "In what year did Nintendo release its first game console in North America?", "1985" },
            { "In the world of video games, what does NES stand for?", "Nintendo Entertainment System" },
            { "In what year was the Nintendo 64 officially released?", "1996" },
            { "What was the most popular video game in the year 1999?", "Doom" },
            { "If you have any kind of console known to mankind, what will your mother call it no matter what?", "A Nintendo" } };

        //printing the question
        System.Console.WriteLine(array2D[randInt, 0]);
        System.Console.ReadKey();

        //taking user input
        string Answer = Console.ReadLine();

        //checking to see if the answer is correct
        if (Answer.Equals(array2D[randInt, 1]))
        {
            //the console exclamation for the right answer given in any scenario.
            Console.WriteLine("Correct Answer! Good job!");
            Console.ReadKey();
        }
        else
        {
            //the console exlamation for the incorrect answer in any given scnario
            Console.WriteLine("Aw man! You got it wrong! Better luck next time :(");
            Console.WriteLine("The correct answer was {0}", array2D[randInt, 1]);
            Console.ReadKey();
        }

    }

Просто удалите System.Console.ReadKey() сверху; 

//Random number generator
        Random rnd = new Random();
        int randInt = rnd.Next(0, 9);

        //Questions array Question/Answer
        string[,] array2D = new string[10, 2] {
        { "Mario Kart is a video game series publish by which company?", "Nintendo" },
        { "What was the first console video game that allowed the game to be saved?", "The Legend of Zelda" },
        { "The Connecticut Leather Company later became what toy company that was popular in the 1980s for its Cabbage Patch Kids and video game consoles?", "Coleco" },
        { "Nintendo is a consumer electronics and video game company founded in what country?", "Japan" },
        { "The first person shooter video game Doom was first released in what year?", "1993" },
        { "In what year did Nintendo release its first game console in North America?", "1985" },

        { "If you have any kind of console known to mankind, what will your mother call it no matter what?", "A Nintendo" } };

        //printing the question
        System.Console.WriteLine(array2D[randInt, 0]);
        //System.Console.ReadKey(); Removed

        //taking user input
        string Answer = Console.ReadLine();

        //checking to see if the answer is correct
        if (Answer.Equals(array2D[randInt, 1]))
        {
            //the console exclamation for the right answer given in any scenario.
            Console.WriteLine("Correct Answer! Good job!");
            Console.ReadKey();
        }
        else
        {
            //the console exlamation for the incorrect answer in any given scnario
            Console.WriteLine("Aw man! You got it wrong! Better luck next time :(");
            Console.WriteLine("The correct answer was {0}", array2D[randInt, 1]);
            Console.ReadKey();
        }
